3D printing machine: for the manufacture of pieces in three dimensions by depositing successive layers of melt.

Additive Manufacturing: manufacturing processes by adding material, most of the computer-aided time.

CAD : Computer Aided Design = includes all the software and geometric modeling techniques to develop, virtually test and realize manufactured products and tools to make them.

Charmille: measure of grain for a grained surface of an object.

Fab Lab : FABrication LABoratory = Community digital workshop open to all (handymen, designers, artists, students, hackers, …). It is equipped with computer controlled machinery must comply with a charter established by the MIT.

Layer thickness : The layer thickness measuring the height of each added material in the additive manufacturing processes or 3D printing based on the layer stack.

Layout : partial or full representation of an object (existing or proposed) in order to test and validate certain aspects. The model can be performed at a given scale, usually reduced or enlarged for easier viewing.

PA : Polyamide: polymer plastic.

PC : Poly-Carbonate: Polymer plastic.

Photosensitive : material which reacts with light radiation.

Polymerization : chemical reaction or process whereby small molecules react together to form molecules of higher molecular weights.

PP : Poly-Propylene Polymer plastic.

Prototype : an original model that has all the qualities and all technical operating characteristics of a new product, but it is also sometimes an incomplete copy of that may be a product.

Rapid Prototyping: making computer-controlled method, which includes a set of tools which, arranged between them, allow to arrive at intermediate representation projects product design : models, prototypes and pre-series.

RIM : Reaction Injection Molding = By creating an epoxy or silicone resin mold (previously from a master model made Stereolithography) prototype can then take shape.

SLA: Stereolithography Stereolithography Apparatus = polymerization of a photosensitive epoxy resin by ultraviolet laser in layers of 0.10 to 0.15mm.
